AUTOMATIC LIQUID-MEASURING DEVICE.

Specification of Letters Patent.

Patented July "4, 1914 Application filed March 28, 1913. Serial No. 757,340.

To all whom it may concern:

Be it known that we, FRANK Sononm and FRANK F. MARSHALL, citizens of the United States, and residents of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Automatic Liquid-Measuring Devices, of which the following is a specification.

Our invention relates to improvements in automatic liquid measuring devices, and has for its object the production of a device of this character, which will be adapted for use especially in bar rooms or saloons where beer or other liquid is sold by the quart or pint, the beer or liquid being drawn from faucets arranged at the inner side of the bar or counter. At the present time considerable time is lost by reason of the fact that a bartender or other person superintending the measuring of the beer or liquid isrequired, after opening the faucet, to remain until the desired quantity has been drawn and then to shut off the faucet by hand. Also, at the present time the bartender or person drawing the beer or liquid is required to exercise his judgment as to the amount of beer or liquid which is drawn by him, there being no definite means of measuring.

It is therefore the object of the present invention, to provide a faucet which may be adjusted to permit of the passage of any desired quantity of liquid therethrough, and which, after being moved to open position, will automatically shut itself off after that quantity of liquid has been drawn.

A still further object is the production of mechanism of the character described which will be of durable and economical construction and efficient in use. Other objects will appear hereinafter.

With these objects in view, our invention consists of the combinations and arrange- Q s 1 said handle, when the device is in use being adapted for manual engagement in swingments of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which, 1

Figure 1 is a front elevation of a liquid measuring device embodying our invent-ion, parts thereof being broken away and shown in section, Fig. 2 1s a top plan view of the device, Fig. 3 is a section taken on substantially line rrm of Fig. 1, the device being arranged with the controlling valve of the faucet closed, Fig. 4 is a view similar to 3, showing the opposite side of the device, the latter being, however, shown adjusted to open the controlling valve of the faucet, parts of the construction being broken away and omitted in order to expose underlying parts, Fig. 5 is a section taken on line i of Fig. 3, Fig. 6 is a sectional detail taken on substantially line e-z of Fig. 5, Fig. 7 is a detail of one of the levers cooperating wit-h the trigger of the device, Fig. 8 is a sectional view illustrating the rearward side of the disk carrying the pins which effect actuation of the trigger, when said disk is rotated, and Fig. 9 is a detail of the water wheel employed in the construction, Fig. 10 is a detail of the means for raising the trigger.

The preferred form of construction as illustrated in the drawings comprises a faucet 1 which is secured to and which projects through a plate 2 which is adapted for fastening upon the support 3 at any location desired. The rearward end 4 of the faucet 1 projects through-the supporting member 8 j a valve 5 of any approved design, operation of said valve being effected by an upwardly extended pivoted arm 6. The arrangement is such, that, when the arm 6 1S 1n a rear- Wardly tilted position or at its rearward terminal of oscillation, as shown in Fig. 3 the valve 5 will be closed, and when said arm is j in a substantially vertical position or at its forward terminal of oscillation, as shown in operatively connected with the operating arm 6 of the valve 5 by means of a link 8,

ing the arm 6 to its forward terminal of oscillation and hence to move the valve 5 to open position. The'handle 7 is provided with buffers 9 which cooperate therewith to absorb jars which are incident to oscillation of said handle. Pivoted at 10 to the plate 2 is a forwardly projecting detent 11 provided at its forward or free end with a shoulder 12 adapted to engage with a laterally projecting pin 13 provided at the uptent to releasing position.

per end of the arm 6, to releasably hold said arm at its forward terminal of oscillation and hence the valve 5 in open position. The arrangement is such, that the under side of the detent 11 remains constantly in engagement with said pin, said pin sliding in con tact with said edge of said detent upon oscillation of said arm, and so that when said arm is moved to its forward terminal of oscillation the shoulder 12 of said detent will automatically drop into position behind said pin toreleasably hold said arm in this posi tion.

Tripping of the de'tent 11 in order to effect release of the arm 6 is secured through the medium of a trigger 14:, the forward end of said trigger being adapted to engage against the under side of a laterally projecting lip 11 formed at the free end of said detent, and so that, when said trigger is moved upwardly, the same will engage said lip and cause upward swinging 'of said do The rearward vertically disposed end 15 of the trigger 1 1 is secured by screws 16 to a plate 17 which is pivoted at its upper end as at 18 to a member 19 which is mounted for vertical movement upon the plate 2 in guide loops 20 which loosely embrace said member-19 at its upper and lower extremities, as clearly shown in the several'views. The screws 16 engage an elongated slot provided in the end 15 of the trigger, such construction permitting of relative vertical movement of the trigger, as will be readily understood.

Mounted upon a studshaft 21 which is secured to and which projects forwardly from the lower end of the member 19 is a disk 22 upon the rearward side of which are provided projecting pins 23. There are a number of pins 23 which are arranged at varying distances from the center of rotation of said disk and spaced circumferentially thereon, as clearly shown in Fig. 8. The lower extremity of the portion 15 of the trigger 14: is positioned for contact with any one of the pins 23 whereby, upon positive rotation of said disk contact of any one of said pins with said lower end 'of the portion 15 of the trigger ltiWlllGllGCt elevation of the latter to cause tripping of the detent 11. Retrograde rotation of the disk 22 is effected by a helical tension spring 24:, which also serves to hold the member 19 at its lower terminal of sliding movement or in contact with a stop constituted by a screw which is threaded for adjustment in a lug 25 formed upon the front side of the plate 2. Positive rotation of the disk 22 in therewith by a reduced hub, as shown. The extremities of the spindle ofworm27 are mounted in suitable bearings 28 and 29, one end of said spindle carrying a water wheel 30 which is mounted in a housing 31 formed at the under side of the faucet 1 just behind the valve 5. The water wheel 30 is'so positioned that the passage of-liquid through the faucet will cause rotation of said water wheel which in turn will impart simultaneous rotary movement to the worm 27. The wings or blades of the water wheel 30 are preferably inclined transversely, as shown in Fig. 9, it having been found that a wheel so constructed is most effective and uniform in the number of rotations which will be imparted theretoin the flow of liquid through the faucet; One side of the housing 81 is closed by a removable head 32 which permits of access to the interior of said housing for the insertion or removal of thewater wheel. At the point of passage of the stem of the worm 27 through said member 32 is provided a suitable packing to prevent leakage. WVith this arrangement it will be seen that upon the passage of liquid through the faucet, with the worm wheel 26 in mesh with the worm 27 such passage will effect rotation of water wheel 30 and hence worm 27, the latter in turn causing rotation of said worm wheel. Rotation ofsaid worm wheel effects positive rotation of the disk 22 moving the pins 23 toward the lower end of the portion 15 of the trigger 14 to cause tripping of the. detent 11 when one of said pins 23 engages with said end of said trigger and causesvertical movement of the latter.

Formed at the upper end of the member 19 is a forwardly projecting arm 33 provided at the under side of the forward end thereof with a curved face '34. Formed at the upper end of the arm 6 is an extension 1 27 in order to permit of retrograde rotation of the disk 22 by theinfiuence of the spring 2 1-. Thus, with-this construction" when the "valve 5 is in closed position the operative connection between the worm 27 and the worm wheel 26 Wlll be broken, this, connection being established only upon forward swinging ofvthe arm 6 to open the valve, in which event. the portion 35 is moved from engagement with the arm 33 permitting the member 19 to move downwardly by gravity aided by the spring 24:. Through the provision of a plurality of or lug 35 adapted, when the arm 6 is moved pins 23 arranged as shown and described, it will be seen that by adjusting the portion 15 of the trigger member so that the lower extremity thereof will contact with a certain one of said pins, the duration of the interval at the expiration of which said trigger will be actuated by the disk 22 in the rotation of the latter may be varied, it being clear that by spacing said pins 23 circumferentially upon said disk, the same will reach their operative positions relative to the lower extremity of the portion 15 of the trigger successively, the pin 23, with the arrangement disclosed, which is closest to the center of the disk being adapted to first reach its operative position relative to said end of said trigger and the pin 23 adjacent the periphery of said disk being the last to reach its operative position upon rotation of the disk 22. In order to adapt said end of said trigger for engagement with the various pins 23 the same is mounted upon the plate 17 which is mounted for pivotal adjustment. Such. adjustment of said plate 17 and hence the lower end portion 15 of the trigger is secured through the medium of a manually operable bell crank lever 36 which is pivoted at 37 upon the plate 2. One end of said trigger is connected by a link 38 with the plate 17, the arrangement being such, that upon vertical swinging of the outer handle-forming end of said lever,

said plate 17 and hence the end 15 of the trigger carried thereby may be adjusted as desired. A notched graduated flange 39 formed at one edge of the plate 2 cooperates with the lever 36 to releasably hold the same in its positions of adjustment, the graduations indicating the quantity of liquid which will flow through the faucet, before the latter is automatically shut off at the various adjustments of said lever. l/Vith this arrangement then, after determining the amount or quantity of liquid which it is desired to draw, the lever 36 is manually adjusted to engage the same with the corre sponding notch in the flange 39 whereupon the valve is opened.

Fulcrumed at 40 to the upper end of the member 19 is a bell crank lever 41 to the outer end of one arm of which is secured a hand or indicator 42 in proximity with the outer end of which is provided a graduated scale 43 adapted to cooperate with said in- 3 dicator, the graduations upon said scale corresponding with the graduatlons cooperating with the notched flange 39. The outer end of the other arm of the lever 41 is conj nected by means of an angular link 44 with the worm wheel. 26, as shown at 45. lVith this arrangement, upon rotation of the worm wheel 26, as above mentioned, the indicator 42 will move simultaneously to indicate the quantity of liquid which is discharged at any particular time.

Cooperating with the handle 7 is a helical torsional spring housed in a housing 46 which is secured upon the front side of the plate 2, said spring being connected with a rocker arm 47. Said rocker arm is connected by means of a link 43 with the handle 7, said spring being adapted normally to hold the same in a position with the valve 5 closed and so that, upon release of the arm 6 by the detent 11, as above described, said spring will immediately rock the handle 7 rearwardly and consequently the valve 5 to closing position. A dash pot 49 cooperates with the handle 7 to absorb any ars which will be incident to the rapid return of the handle 7 to closing position under the infiuence of the returning mechanism just mentioned. The forward end of the piston rod 50 of said dash pot is pivotally connected with the handle 7, as clearly shown in Fig. 3.

With a device then of the construction set forth, when it is desired to operate the same it is first required, after determining the quantity or amount of liquid which it is desired to draw, to adjust the hand operable lever 36 to correspond with such amount,

I as indicated by the graduations cooperating with the flange 39. the valve handle 7 1s rocked forward causmg After this adjustment opening of the valve 5. Said valve will be held in open position by the detent 11 which will automatically move into engagement with the laterally projecting pin 13 of the valve arm 6 when said valve is in fully opened position. Immediately upon forward swinging of the arm 6 which movement thereof is effected upon rocking of the handle 7 to open position, the upper end or extension 35 of the arm 6 will move from engagement with the arm 33 provided at the upper end of the member 19 permit-ting of slight downward movement of the latter.

This movement of the latter causes engagement of the worm wheel 26 with the worm 27, and so that upon rotation of said worm .wheel such as is imparted thereto through rotation of the water wheel which is operated by the passage of liquid through the faucet, the disk 22 will be caused to positively rotate carrying the pins 23 thereof toj l ward the lower extremity of portion 15 of Zthe trigger 14. When the desired quantity of liquid has flowed through the faucet, one of the pins 23 will contact with the lower lend of the portion 15 of the trigger 14 and cause movement of the latter upwardly to effect tripping of the detent 11. Upon tripping of said detent the arm 6 and handle 7 and hence the valve 5 will be moved to clos- {ing position under the influence of the clos- 5 ing mechanism 46. Thus with this arrange- Tment in use it will only be required to ad- .just the mechanism to the amount of liquid which it is desired to draw, and then to I open the valve, the closing of the valve after the desired quantity of liquid has flowed through the faucet being automatically effected.
